feat(tone): add a Tone Generator tool (closes #90) - #91
Merged
Conversation
A simple pure-tone generator built on the Web Audio API — no dependencies, no licensing. Play a continuous tone for tuning, testing speakers, or a reference pitch. - Frequency by slider or exact hertz (20–20,000), or snap to a musical note + octave (equal temperament, A4 = 440); a live readout names the nearest note and how many cents sharp/flat it is. - Sine / square / sawtooth / triangle waveforms, volume, and A4 / 1 kHz presets. Start and stop ramp the gain so there is no click. - Pure pitch maths (`tones.js`) and the oscillator composable are unit-tested (the AudioContext is injected). - Registered as the `tone-generator` tool. The search dialog no longer caps its list at 20 so every tool stays reachable. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
